1 INTRODUCTION
1.1 KLIC-LG1
KLIC-LG1 from Zennio is a gateway that provides full-duplex communication between
the KNX home automation system and LG air-conditioning systems through the 3-wire
gateway provided.
Because of this bidirectional communication, the air conditioning system can be
controlled from the home automation system in the same manner as it is through its own
controls. Moreover, the actual status of the unit can be monitored and periodically sent
to the KNX bus to inform other devices.
The most outstanding features of KLIC-LG1 are:
Bidirectional control of LG A/C units through the connection wires provided
by LG: R (supply voltage, 12V), Y (communication), B (GND).
Control of the main functions of the A/C unit: On/Off, temperature, mode of
operation, fan speed, position of the flaps, etc.
Error management to handle specific error codes from the A/C unit itself as
well as any communication issues that may arise.
Up to five scenes.
Three analogue-digital inputs, for the connection of temperature probes,
motion detectors or binary pushbuttons or switches.
10 customisable, multi-operation logic functions.
Heartbeat or periodical “still-alive” notification.

1.2 INSTALLATION
Figure 1. Element scheme.
KLIC-LG1 connects to the KNX bus via the corresponding built-in terminal (5). Once the
device is provided with power from the KNX bus, both the physical address and the KLICLG1 application program can be downloaded.
This device does not need any external power as it is entirely powered through the KNX
bus.
The remaining elements are described next.
Prog./Test button (2): a short press on this button will set the device into the
programming mode, making the associated LED (1) light in red.
Note: if this button is held while plugging the device into the KNX bus, the
device will enter into safe mode. The LED will blink in red every 0.5 seconds
Analogue-Digital Inputs (3): input ports for the stripped cables of external
elements such as switches, motion detectors, temperature probes, etc.
Terminal connection, RYB (4): wires that will connect KLIC-LG1 to the A/C
unit. The other end of the cable, therefore, is intended to be connected to the
corresponding connectors in the PCB board of the internal unit.

Important:
If intending to control the A/C unit both through its incorporated wired remote
control and through KLIC-LG1, it must be taken into account that orders sent
from the wired remote control will have a higher priority than those sent
through KLIC-LG1.
If there are several indoor units connected to a single outdoor unit, all of
them must work in the same mode (heating or cooling). If they work in
opposite modes, the CH 07 error will appear.
For detailed information about the technical features of KLIC-LG1, as well as on security
and installation procedures, please refer to the device Datasheet, bundled in the device
packaging and also available at http://www.zennio.com.
1.3 START-UP AND POWER LOSS
Depending on the configuration, some specific actions will be performed during the
device start-up. The integrator may set up an initial status to be sent to the A/C unit after
the bus power recovery, and whether certain objects should be sent to the bus after the
power recovery, as described in later sections.
On the other hand, when a bus power failure takes place, the device will interrupt any
pending actions, and will save its state so it can be recovered once the power supply is
restored.
Notes:
After a bus power failure, it can take up to a minute to establish the connection
between KLIC-LG1 and the A/C unit.
The configuration of the remote wired control will be sent if this control is
plugged after KLIC-LG1.

2 CONFIGURATION
2.1 GENERAL
The general configuration of the device consists in enabling the specific functionalities
that will be required during normal operation:
Heartbeat or periodical “still-alive” notification.
Inputs: see section 2.2.
Logic functions: see section 2.3.
AC gateway: see section 2.4.
The latter entails all functions specific to KLIC-LG1, i.e., all the functions related to
interfacing with the A/C unit and to the management of the climate control system.
ETS PARAMETERISATION
After importing the corresponding database in ETS and adding the device into the
topology of the desired project, the configuration process begins by entering the
Parameters tab of the device.
The General screen is shown in the first place, containing the following parameters:
Figure 3. General.
Enabling Inputs, Logic Functions and AC Gateway brings additional tabs into
the menu on the left. These functions and their parameters will be explained in
KLIC-LG1

later sections of this document. Please, note that AC Gateway is permanently
enabled.
Heartbeat (Periodical Alive Notification): this parameter lets the integrator
incorporate a 1-Bit object to the project (“[Heartbeat] Object to Send ‘1’”) that
will be sent periodically with value “1” to notify that the device is still working
(still alive).
Figure 4. Heartbeat.
Note: The first sending after download or bus failure takes place with a delay
of up to 255 seconds, to prevent bus overload. The following sendings match
the period set.
Regardless of the above parameters, the following objects are available by default:
“[AC] On/Off” and “[AC] On/Off (Status)”: allow switching on (value “1”) and
off (value “0”) the A/C unit or reading the current status, respectively.
“[AC] Temperature Setpoint” and “[AC] Temperature Setpoint (Status)”:
allow setting the desired temperature setpoint or reading the current value,
respectively. See section 2.4.1 for further options.
“[AC] Mode” and “[AC] Mode (Status)”: allow setting the desired operation
mode (either Automatic, Heating, Cooling, Fan or Dry) or reading the current
mode, respectively. See section 2.4.1 for further options.
“[AC] Speed: Percentage Control” and “[AC] Speed Percentage control
(Status)”: allow setting the desired speed or reading the current speed,
respectively. See section 2.4.1 for further options.
“[AC] Operating Time”: shows the time in hours that the A/C unit has been
working. See section 2.4.1 for further options.

“[AC] Reference Temperature (Status)”: shows the temperature that is being
used by the A/C unit as reference. See section 2.4.1 for further options.
Several error objects. See section 2.4.6.

2.2 INPUTS
KLIC-LG1 incorporates three analogue/digital inputs, each configurable as a:
Binary Input, for the connection of a pushbutton or a switch/sensor.
Temperature Probe, for the connection of a temperature sensor from Zennio.
Motion Detector, for the connection of a motion detector (models ZN1IO-
DETEC-P and ZN1IO-DETEC-X from Zennio).
Important: older models of the Zennio motion detector (e.g., ZN1IO-DETEC
and ZN1IO-DETEC-N) will not work properly with KLIC-LG1.
ETS PARAMETERISATION
When Inputs has been activated in the General parameters screen, the following dropdown lists will be available for the selection of the specific functions required.
Figure 5. Inputs. Configuration.
All inputs are disabled by default. Depending on the function selected for each input,
additional tabs will be included in the menu on the left.
2.2.1 BINARY INPUT
Please refer to the “Binary Inputs” user manual, available in the KLIC-LG1 product
section, at the Zennio website (www.zennio.com).

2.2.2 TEMPERATURE PROBE
Please refer to the “Temperature Probe” user manual, available in the KLIC-LG1
product section, at the Zennio website (www.zennio.com).
2.2.3 MOTION DETECTOR
It is possible to connect motion detectors (models ZN1IO-DETEC-P and ZN1IO-DETEC-
X from Zennio) to the input ports of KLIC-LG1.
Please refer to the “Motion Detector” user manual, available in the KLIC-LG1 product
section, at the Zennio website (www.zennio.com).
Notes:
The ZN1IO-DETEC-P motion detector is compatible with a variety of Zennio
devices. However, depending on the device it is actually being connected to,
the functionality may differ slightly. Therefore, please refer specifically to the
corresponding product section to obtain the aforementioned document.
Motion detectors with references ZN1IO-DETEC and ZN1IO-DETEC-N are
not compatible with KLIC-LG1 (may report inaccurate measurements if
connected to this device).
When connected to KLIC-LG1, the rear micro-switch of model ZN1IO-DETEC-
P should be set to position “Type B”.
